Popis:	A direct-deposition Fourier transform infrared (FT-IR) system has been evaluated for applicability to gas chromatography (GC) and supercritical fluid chromatography (SFC) of environmental analytes. A 100-μm i.d. fused-silica transfer line was used for GC, and a 50-μm transfer line with an integral restrictor was used for SFC. Minimum identifiable quantities for GC/FT-IR ranged from 0.5 to 2.0 ng. This is over an order of magnitude better than those reported for light-pipe FT-IR by this laboratory
